(Originais Teachy 2023) - Question Medium of Physics

A car initially travels at 20 m/s, maintaining a constant speed on the highway, going from point A to point B, which is 2000 meters away from A. On the return from point B to point A, the car follows the same trajectory, but with a speed of 30 m/s. Considering that the trajectory from point A to point B is straight and can be represented by an Aristotelian line, what was the average speed of the car during the entire round trip (A-B-A)?
24 m/s
20 m/s
30 m/s
22 m/s
25 m/s

A young person throws a rubber ball to observe its trajectory and height h, in meters, reached over a certain interval of time t, in seconds. During this interval, the ball bounces on the ground several times, progressively losing height. Part of its trajectory is described in the following figure. In his observations, how many times can the young person see that the ball reached the mark of 35 meters?
